GATE OPENING AND CLOSING DEVICE.

Specification of Letters Patent.

Patented May 4, 1909.

Application filed October 3, 1907. Serial No. 395,765.

To all whom "it may concern:

Be it known that 1, JOHN R. KERR, of the city of Brantford, in the county of Brant and Province of Ontario, Canada, have invented certain new and useful Improvements in Gate Opening and Closing Devices; and l hereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to an operable means by which a gate can be opened and closed, and it consists of a means comprising two gate opening cords and two gate closing cords connected to the gate and ar ranged in sets extending beyond the opposite sides of the latter and passing over suitably positioned guide pulleys whereby the cords at each side can be employed to respectively open and close the gate. In the case of very light gates an automatic closing device is provided.

For an understanding of the invention reference is to be had to the following description and to the accompanying drawings in which Figure 1, is an elevation of the gate showing the attachment of the gate opening and closing cords. F 2, is a plan view showing the arrangement of the gate opening and closing cords respectively. Fig. 3, is a similar View to Fig. 2, showing a modification of the construction shown in Fig. 2. Fig. 4, is a perspective view of one of the posts shown in Figs. 2, 3, and 5. Fig. 5, is a plan view of a device for effecting the automatic closing of light gates.

Like characters of reference refer to like parts throughout the specification and drawings.

Referring to Figs. 1 to 3 of the drawings, 1 is a lever fulcrumed to the guide post 1, upon which the gate is swung. The lever 1, when the device is attached to gates already in use, may consist of a bar or pole having a slot 14 to receive the fulcrum 13, on the gate post 1*. One end of the lever is at 'tached to the latch end of the gate and this tioned according to the weight of the gate. it pulley 5, provided on the gate and over this pulley passes a cord 1, attached at one cud to the latch 23, of the gate which is shown as a drop latch but may be of any desired construction. The cord i, is attached at ils other end to four other cords 8, 9, 10 and 11, of which 8 and 9 are the opening cords and 10 and 11 are the closing cords. These opening and closing cords are disposed as follows :ln Fig. 2, the cord 8, is shown to pass over the pulley (3 to the pulley 15 on a post 16, situated so that the end of the lever 1, will come ()PljiOSltG, and a few inches away from it when the gate is fully opened. The. cord 8, passes from the pulley 15, to a pulley 17, on a post .18, situated from 90 to 30 feet from the gate on the opposite side of the post 1 to the post 16, and a weight 19, is attached to the end of the cord 8 to keep it continually taut. The cord 9 passes over a pulley 20 on the post 16 and thence to a pullcy 21 on the post -22, on the same side of the gate post 1 as the post 16, and placed in a similar position relatively to the gate post 1 as the post 18. If desired the cord 9, can be led directly from the pulley (i to the pulley 21. A weight is provided for the cord for the same purpose as the cord 19. The cord lOpasses over the pulley 7, to a pulley on a post 25 situated in rear of and approxin'iately in line with the gate post 1,

tion. The catch 8 is either weighted to counterbalance the weights 19, 23, 27, 30,

or is provided with a spring for that. pur pose.

in the modification shown in Fig. 3, the pulleys 6 and 7 are dispensed with and replaced by a longitudinal lover arm 36, piv oted to the lever 1. near the rear end of the latter. The lever arm 36 has a curved end 38 to the rear side of which is attached the latch cord 4- which passes to the latch 3. The gate opening and closing cords 8, 9, 10, and 11, are each attached to the other end of the lever arm 36, and are disposed over the pulleys 15, 20, 2 1, and 28, respectively and over the various posts in the manner above described with reference to Fig. 2. \Vhen it is desired to open the gate either the cord 8 or the cord 9 is pulled, whereby the gate then being in its closed position, the lever arm is rocked about its pivot 37 to pull the latch cord 4 and raise the latch. The continued pull now opens the gate. The closing of the gate is effected in an. exactly similar manner with the exception that the cord l0 or the cord 11 is operated. The pivot 37 of the lever 36 is preferably placed toward the end 38 thereof, so that the pull upon the cord at is increased by the leverage of the arm 36. One of the advantages of this modification consists in the fact that the pulls on either side of the lever 36 are approximately balanced when no cord is being operated, and the latch cord 4- is under very little strain. For iron, wire or very light gates, the closing cords may be dispensed with, and a cord 33, may be attached to the end of the lever 1, and led over a pulley 34 on the post 25 (Fig. The weight 35, is attached to this cord, said weight being sutficient by its pull on the lever 1 to close the gate. With this device it is only necessary to open the gate by pulling on the cord 8, on one side, and after passing through, to pull on the opening cord 9 sutficiently to raise the latch 3 engaging the post 31, wl'iereupon the weight 35 will close the gate.

The operation of the device shown in Figs. 1, 2, and 3 is as follows :Suppose a driver wishes to pass through the gate from A to B, he pulls on the cord 8, and the pull being communicated to the cord 4, first raises the latch 3, and then effects the opening of the gate. When the gate is fully opened, the latch engages with the post 31, and the gate cannot close until the driver, after passing through, pulls the cord 11 which first raises the latch 3, and then closes the gate. A post with its weight and cords is shown in Fig.

lVhen passing from B to A exactly the same procedure is followed except that the cord 9 is pulled to open the gate, and the cord 11 to close it.

Having thus fully described my invention what I claim as new and-desire to secure by Letters Patent is 1.
